The only thing that could have distracted Michael Buble’s velociraptor stalker is an iPhone OS 4 announcement, and guess what just came through the post? US journalists are reporting that Apple has sent out invitations to an event this Thursday at 6pm for a preview of the next iPhone OS software update.

Word on the street is that the next iPhone update will include multitasking (aka being able to run more than one app at the same time) and various user interface updates. We can’t wait to hear what iPhone OS 4 will offer and if it is multitasking then the velociraptor told us that he’d stop stalking Buble for at least a day.
